What is the temperature on Saturn?

A:

Quick Answer

The effective surface temperature of Saturn is minus 288 degrees Fahrenheit. The planet's longitudinal temperatures remain fairly constant, varying only about 18 degrees between its northern pole and its equator, but its chemical composition causes the temperature to increase dramatically closer to the center of the planet.

Because the planet is so far from the sun, most of Saturn's heat is drawn from the liquid hydrogen and other elements near its core rather than the sun. At its center, the temperature is estimated to reach 21,000 degrees Fahrenheit. In the middle regions, between the liquid center and outer ice, the temperature varies from 26 degrees Fahrenheit in the outer layers to 134 degrees Fahrenheit in the lower layers.
